Diddy and supermodel Kate Upton have been spotted sharing a steamy kiss. The media mogul who finally claimed singer/model Cassie as his girlfriend was spotted getting “hot and heavy” with the curvaceous blonde.

One “eyewitness” saw them “sucking face” in a VIP room at Club LIV in Miami Beach on March 24.

Earlier that night, Diddy tweeted he was hosting a party:

“Miami … Ain’t no party like a @iamdiddy party … Meet me at Club Liv 2nite #CIROCBOYZ in the building!!!”

Stunning Upton, 20, soon joined Diddy, 43, in the VIP section where they partied together late into the night. According to the NY Daily News, the two reportedly met in New York on Thursday for an intimate meal at the Bowery Hotel.

Kate recently broke up with star Detroit Tigers pitcher Justin Verlander, and Diddy was recently house-hunting with Cassie, which leads me to believe, Cassie will always be the side chick.
